Systems exhausting toxic, flammable, paint or corrosive fumes or dust. Commercial kitchen hoods used for collecting grease or smoke. Where > 60% of outdoor heating energy is provided from site-recovered or site solar energy. Heating energy recovery in climate zones 1 and 2. Cooling energy recovery in climate zones 3c, 4c, 5b, 5c, 6b, 7, and 8. Where largest exhaust source is < 75% of the design outdoor airflow. Systems requiring dehumidification that employ energy recovery in series with the cooling coil. Systems operating < 20 hrs/week at outdoor air % in Table The last exception refers to systems like wrap around heat pipes providing reheat after the cooling coil.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
